'melted' tape roller

Hi folks, I've seen this phenomenon on the likes of printers etc but I've never seen it on a tape drive. Basically the rubber that used to surround the wheel that controls FF/REW/Play functions on the tapedeck in my newly acquired Sharp MZ80B has melted to a sticky black compound that's run down the housing and gummed up the tape wheels. Pix at http://www.wowrarelook.co.uk/DSCF5821.JPG (244k) front of housing showing icky stuff http://www.wowrarelook.co.uk/DSCF5812.JPG (27k) control wheel Note shiny surfaces where there shouldn't be shiny surfaces :) I'd assume that the tape mechanism was a standard one but the question is, can I still get the part seen in DSCF5812.JPG since it appears that's all that's at fault?
